Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603098, here are decompositions:

19 + 31603079 = 31603098
71 + 31603027 = 31603098
89 + 31603009 = 31603098
139 + 31602959 = 31603098
167 + 31602931 = 31603098
181 + 31602917 = 31603098
199 + 31602899 = 31603098
239 + 31602859 = 31603098

Showing the first eight; more decompositions exist.
